Abstract: Processes integrating electric heaters or other heating sources for heating of liquid and two phase hydrocarbon streams resulting in reduced CO2 emissions are described. The processes shift a portion of the fired heater duty to an electric heater or other heat source. All or a portion of a vapor stream from a two phase separator is heated or superheated by an electric heater or other heat source to provide sufficient temperature that the heated/superheated vapor stream acts as a heat source to a bottom or side draw stream from a column. The preheated bottom or side draw stream is sent to the fired heater.

Abstract: Processes and apparatuses for heating a hydrocarbon process stream, with an electric heater to provide a portion of the heat requirement necessary for a chemical reaction to occur to one of the components of the hydrocarbon process stream. The electric heater may be used between two reaction zones which are arranged on top of each other. Additionally, reaction zones may be in reactors which are arranged in a polygon.

Abstract: Processes and apparatuses for heating a process fluid. The process fluid flow through a convection section and then a radiant section. The radiant section produces heat and flue gas from the combustion of the fuel. The flue gases flow to the convection section to provide the heat in the convection section. The conduits in the convection section are straight. All of the fluid that passes through the convection section also passes through the radiant section.

Abstract: A new process and apparatus for ethanol dehydration combines a fired heater with a dehydration reactor in a single vessel. The reactor provides catalyst tubes in a firebox. The catalyst may be added to and withdrawn from the catalyst tubes. The apparatus reduces equipment account substantially while holding the reaction to isothermal conditions.

Abstract: Processes and apparatuses for heating a hydrocarbon process stream, with an electrical heater to provide a portion of the heat requirement necessary for a chemical reaction to occur to one of the components of the hydrocarbon process stream. The electric heater may be in series or in parallel with a second, or main heater. The electric heater may be used between two reaction zones or between a feed exchange heater and a first reaction zone. The electric heater preferably provides between 5 to 40% of the heating requirement for the process stream.

Abstract: Processes and apparatuses for heating a feed stream for a reactor which has a charge heater. At least one process stream provides heat so that a pre-heated feed stream passed to the charge heater is a vapor stream. The process stream may be the heated stream from the outlet of the charge heater. Alternatively, the process stream may be the effluent stream from the reactor that has been heated.

Abstract: A fired heater has two cells segregated by an insulative wall. A first plurality of burners are located in the first cell and a second plurality of burners are located in the second cell. A radiant tube extends from the first cell to the second cell for carrying a fluid material through the heater to heat the fluid material. The flow of fuel to the burners in either the first cell or the second cell can be terminated to accommodate lower heater duty when demand is lower.
